T o all whom it may concern Be it known that-I, VERNON RoYLn, a citizenof the United States, and resident of Paterson, in the county of Passaicand State of New Jersey, have invented a new and useful Improvement inPower-Saws, of which the"following iS a specification.

This invention relates to a power saw, with the object in view of'Aproviding such an apparatus which is rigid and compact in structure, isadapted to a wide range of uscfulness, and in which the work table andparts carried thereby are fitted with means for setting and maintainingthe samel in different and accurate adjustments with respent totlie'saw. i

AnotherA object consists in providing certain 'improvements in the form,construction and. arrangement of the several parts whereby the abovenamed and other advan` tages may be effectively attained.

A A practical embodiment of my'invention' is represented in theaccompanying ydrawings, in which,

Fig. 14 represents a plan view, partly inr section, of the partsshown inFig. 13, and

Fig. 15 represents a horizontal section, partly in plan view, showingthe said parts in a different position.

Referring to the preferred form shown in Figs. 1 to 12, inclusive, theapparatus comprises a base 1 which may be secured to the floor or anyother suitable support, by lag screws 2, in a well understood manner.

lThe main frame of the ap aratus consists of a hollow pedestall 3. Thispedestal` may be composed of some appropriate material,

,such as cast iron, and is preferably friied of a single casting. It isfitted to be secured From the foregoing construction, it will be seenthat the saw is mounted directly upon the top of the main frame orpedestal, and that its 'bearings and spindle may be easily removed for'repair or adjustment. This arrangement provides the advantages ofrigidity4 and accessibility which areI always desirable in apparatus ofthis class.Y

The saw proper is denoted bv 1 1, and'vmay belocked in position upon itsspindle 12by the cheeks 13, 14, the latter of which is actuated by aclamping-nut 15 threaded onto the end of the spindle 12 (see Fig. 5).

The said spindle has an enlarged Vleather Icovered hub 16 whichserves'as -a pulley for the engagement of the driving belt 17 whichlatter passes downwardly through a channel 18, (see Fig'. 7), fashionedin rear of themain pedestal 3, and engages e drive pulley 19-that isfixed upon the end ofa countershaft 20 which is connected, in the usualmanner, with anelectrlc motor 21 (see The motor 21 is secured to abracket 22 by suitable cap s crews 23, and the bracket 22 is providedwith a hub portion 24 that is .rotatably mounted upon a stub shaft 25that is fixed in one side of the pedestal 8, near the lower partthereof, by a nut 26, (see Figs. 5 and 6). A nut. 27 serves to hold thebracket hub on the stub shaft. The upper pait of the hub 24 has a flange28 in which is formed an arcuate slot 29 (see Fig. 3), which is fittedfor enga-gement with a lockingscrew 30 that takes into the wall of thepedestal 3. As a result of the above construction, the locking screw 30may be loosened, whereupon the weight of the motor and bracket willcause the latter to swing downwardly a siiflicient distance toautomatically tighten the driving belt 17.

)Vlien in this position, the screw BO may be.

turned to securely hold the parts.

The upperpart'of the main pedestal 3 isl bulged both in front and rear,`as clearly shown at 3l (see Fig. 4), in order toprovide an enlargedportion adjacent to and conforming substantially with the lower part ofthe saw l1; and a skeleton dust cover 32 (see Fig. G), is hinged, asshown at 33, to the upper .front part of the bulge or large portion 31,so as to constitute a closure for the major part of the top of the saidenlarged portion of the pedestal.. This dust cover has an opening 3-1which is designed to surround the saw 11, and it will be understood thatthe said cover is easily removable by taking out theihinge pintle 35, sothat another cover having an opening 34 of different size may besubstituted therefor as the nature ofthe material being operated uponmay prescribe. In any case. the cover which is in position may be swungupon its hinge 33, by seizing the finger clip 3G in a well understoodmanner, so as yto expose they parts below the saw when desired.

The part ofthe main pedestal 3, immediately below the bulge 3l. has apair of slanting ribs 37 .(see Fig. el) which extend Y rearwardly to aspout or chip kchute 58. that Vprojects downwardly from the back of. the

pedestal 3 and is arranged to enter an appropriate aperture formed inthe chip boaY 39 that is removably secured to the pedestal 3 bycomplementary clips 4d. provided for the chute 38 and is fixed to thepedestal 3 by a screw 42. The ribs 3T are fitted to supporta suitablepartition such as a piece of wood 37? This construction assists in theoriginal cast-ing of the pedestal, and enables the partition to beeasily removed when worn. As a result of this arrangement, the part ofthe pedestal which surrounds the sawll is formed in the shape of afunnel for receiving and projecting the chips and dust into the box 3l).B V having tliechip box removably connected with the apparatus by theclips -I-l). I render its detachment for emptying a simple matter;

and by securingat the rear ol' the pedestal.'

the device is made more sightly and the attachment of a suction hose, ifdesired, fa-

`cross-heads 54,

A cover 4l isV cilitated, while the operative is in no wise hampered bythe chip box or its attachments.

The work table is indicated by -l-l, and may be formed. as is customary.of a single casting of 'iron or other suitable metal, appropriatelywebbed for reinforcement. It is pivotally mounted at the rear of themain frame or pedestal il. by a hingey member -l-l (see Fig. (3). whichis secured to' the under side of the table by bolts 45, lil. This hingemember is engaged by ti'unnions l?, 48 which are threaded into lugs if).50. integrally formed upon a bar 5l that is secured, by means of capscrews 52, 53, to a pair of The lugs 49, 50. are developed into stops492:, 5W, for limiting the swinging n'iovenient of the table 43.

The cross-heads 5-l, 55, are bored for en- -the arms 58, 59. At thecenter part of each cross-head 54, 55, a pitman 64, 65. is connected,and the lower ends of said pitmen engage cranks 66, 67, (Fig. 5) thatare formed integrally with the hubs 68, 69, .rotatably mounted upon across-shaft 70 which is `iournaled in the walls of the pedestal 3. Thehub 69 has a segment gear 'Tl integral therewith. which gear is enmeshedwith a worin 72 that is fixed on the end of a shaft 75l mounted in abearing 74 (see Fig. l).

.which secured to the side of the pedestal 3 by screws 75. A hand wheel76 is fixed to the forward end of the shaft 73, and serves `for themanual operation thereof.

lt will beV clear from the foregoing description that. by actuating thehand wheel 76. the segment gear 7l will be caused to swing arcuately,thereby turning the crank '(56, and` through the shaft 70, also turningthe crank 67. This simultaneous movement of the cranks G8, (ST.similarly actuates the pitmen 64, 65, thereby raising or lowering. asthe. case may be, the cross-heads 54. 55, and hence the work table 4B.and parts carried thereby. During this movement the through-bolts 5G, 57and guide rods 60, 6l. will slide freely in the base l and bosses 5S.59, GO. G1. Thus. by-operating the hand wheel 76, the work table 43. andhence the work resting tbereiqioii. may be adjusted to any suitableheight with respect to the saw ll. as the nature of the work mayrequire.

ln theworlc table -l-fl there is fitted a tliioat-'ilate 77 which isappropriately slotted for the passage ol the saw l'l thereaol l'Sllmechanism for regulating the same. is collecthrough.l The under side ofthe table, im-

? mediately below the throat plate 77, is provided with a pair ofdoveta'iled lgrooves 78 that are designed to receive corresponding partsformed upon chip delectors 79, 80, whereby the latter may be removablyset in position beneath the throat plate and thus adjacent one edge. ofthe saw. Thumb screws 81 are fitted in'the chip defiectors v erated uponmay require. From the inverted plan view shown in Fig. 11, it will be'seen that the grooves 78 converge rearwardly with the result that theselected chip defiector may simply be slid into the said grooves untilit automatically comes to a stop in the proper relationship with respectto the saw, at which point it may be fixed by'the thumb screw 81;

When the table 43 is lowered into operative position, as shown in Fig-4,it will bel observed that the chip delector extends downwardly into thebulge 31 so as to insure the projection of the chips or dust into thesaid part of the pedestal 3 and to impart to the same the properdirection of movement for ejection through the chute 38. The uppersurface of the work table 43 has suitable grooves 82, 83, 84, 85, formedtherein for the reception of dimensioning, bev# cling and miteringgages.. The dimensioning gage is denoted by 86, and is shown in y Figs.l'and 2 as fixed inoperative position on the work table. This gage is ofthe form and construction shown and described in my copendingapplication Serial No. 25063` filed April 30, 1915, and hence it willnot be herein described, as its construction is not a part of theinvention herein set forth.

. The beveling gage and the miteiing gage which I contemplate using withthis appa- ,ratus are of the form and construction shown respectively inmy applications Serial No. 140,590, filed January 4, 1917, and No.

140,589,fi1ed January 4, 1917, Aand hence they will not be shown anddescribed herein as their structures constitute no part of the presentinvention. Suitable means for actuating the dimensioning and bevelinggages, with micrometer tively denoted as 87 in Fig.` 1. The constructionof this means is clearly shown and described in my said copendingapplication Serial No. 25063, filed April 30, 1915, and

therefore it will-not be shown in detail or described herein, as itsspecific construction forms no part ofthisinvention.

In order to accommodate the gages which are not in use, and to suitablysupport them in convenient position, I` provide a double' j of the tableconsists of pins 91, 92, (see Figs. 3, 4,-6 and 7) which are threadedinto extensions 93', 94, that are integral with the cross-heads 54, 55respectively. Nuts 95, 96, may be provided for securing the pins l91,92, in any desired position. For elevating or depressing 'either rearcorner of the table 1, set screws-97, 98, are provided,

and are threaded into lugs 99, 100, which are integral with thecross-heads 54, 55, respectively. These set screws 97, 98, bearA againstthe under side of the bar 51 which supports the table 43, and verticaladjust-l ment is permitted to either end ot said bar,

and hence to the.table, by elongating theapertures in the said barthrough which the cap screws52, 53, pass, as shown in dotted lines Fig.3.

The meansv for adjusting the table later ally with respect'to the saw,consists of the pintlesf47, 48, which may be rotated in oppositedirections for accomplishing this purpose, the said rotationserving tomove. the hinge member 44 in either direction between the lugs 49, 50, acertain amount of l play being allowedV for this movement.

In order to swing theV table in a horizon tal plane, it is simplynecessary to loosen the cap screw 46 and tap-'the table with a suitableimplement in the desired manner. The elongated aperture in the hingemember 44 permits of this swinging movement and, when the desiredadjustment hasbeen attained, the cap screw 46 `may again be set intolocking position.`

From the immediately preceding ,description, it will be seen that I haveprovided' means for universally adjusting the table, and hence the work,with respect to the saw` -for maintaining proper relationship betweenthe saw and the gage supporting the work.

As a-.matter of convenience in the removal of the saw 11, I provide anend wrench 101 (Fig..7) which is loosely hung at 102 on the`V` front ofthe pedestal 3, in position to be`V` 'swung over into engagement withthe angled portion 103 of the saw spindle, for holding the same againstrotation while the end wrench is used to loosen the nut 15,

andl while another saw is being adjusted l or the same one replaced, andthe said nut '45 the base 1.

15 again screwedhome. The two positions of the wrench 101 are shown infull and dotil ingv boa; having bearings therem for the ted linesrespectively, in Fig. 7.

It will be understood that the electric motor 21 will obtain its powerfrom a suit- .able source (not shown), and I prefer to have it.connected by means of wires 104 with an electric starter 105 which issecured to the through-bolt 57 by a pair of collars 106, which starter Ialso prefer to have of *'20 and is denoted by 107. It is bifurcated andprovided with bearings for receiving a countershaft 108, which has fixedto Vone end thereof a drive pulley 109 and also carries the customaryfast and loose pulleys 110, 111, respectively, Afor engagement with abelt running :fromy a suitable source of power, not shown.

Mams is proviaa for shifting the tea, which means consists of a beltshifter 112 Ak that'is mounted to slide on alrod 113 which is fixedbetween the bifurcations of the bracket 107. Guide lugs 1123, formedintegral with the shifter, engage a web 107* and serve to prevent theshifter from moving in a rotary direction on lthe rod, which f rotarymovement might tend to cramp th'e shifting lever. An articulatedshifting lever 114 is pivoted to the said shifter at 115. It is alsooscillatably fixed to a pin i .40 116 which depends from the'bracket107.

At this point a stud 117 projects laterally from the lever 114 forpivotally receiving one end of an operating pedal 110` the other end ofwhich rests upon a track v119 'upon It will be seen that by shifting thepedal 115 laterally in one direction, the l power belt will be engagedwith the fixed pulley, and by reversing the position of the pedal, thesaid belt will be engaged with the loose pulley. This construction isdesigned to be used with my apparatus when it is desired to take powerfrom anordif nary factory shaft.

It will be understood that various changes i may be resorted to in theform, construction and arrangement of the several parts withoutdeparting from the spirit and scope of my invention, and hence l do notintend to be limited Ato the specific details herein shown anddescribedexcept `as they may be included in the claims.
